Can I do a jquery-tmpl each over object properties

阅读更多关于 Can I do a jquery-tmpl each over object properties

问题 The template {{each}} directive works great for iterating over an array like this: var myArray = ["a","b","c"]; I'm wondering if there is an equivalent for iterating over object properties, i.e.: var myObj = {"propOne": "a", "propTwo": "b", "propThree": "c"}; I'd like a template that would let me output as <ul> <li><span>propOne</span><span>a</span></li> .... etc For bonus points I'd like to use this template from KnockoutJS. 回答1: Actually {{each}} will walk through properties on an object.

Knockout value binding doesn't work with jquery autocomplte. How to get it working? I have a template: <input type="text" class="autocomplete" data-bind="value: viewModelObservableValue" name="MyValue" /> After template rendering I am applying jQuery autocomplete on an input.

I wanted to try out jQuery Templates after being inspired by these 2 blog postings http://encosia.com/2010/11/10/composition-with-jquery-templates-why-and-how/ http://encosia.com/2010/10/05/using-external-templates-with-jquery-templates/ Well, it's not quite working for me.

阅读更多关于 defining new variable within jquery template

问题 Is it possible to define a new variable within a jquery template? I read the official jquery template docs but could not find anything on this. I tried something like {{ var xxx=123 }} but it didn't work. Finally I am using a hack by doing ${$item.xxx=123,""} and later using $item.xxx but I am sure it is not the best approach... 回答1: I don't think that doing the $item approach is too bad. It is consistent with where you would look for variables that are passed in via the options parameter to
